Services

• Excellent corrosion resistance, particularly against salt spray, due to chromic acid’s natural corrosion-inhibiting properties.
• Ideal for assemblies with overlapping joints, recesses, or small blind holes, as residual chromic acid does not need to be fully removed.
• Provides a strong base for paints and organic coatings, improving adhesion.
• Thinner coatings (0.00003–0.0001 inches) that meet corrosion resistance requirements without significantly affecting fatigue strength.
• Can be dyed, typically with darker colors, despite being thinner and less porous.

• Lower abrasion resistance compared to other anodizing processes.
• Limited to alloys with less than 5% copper or 7% silicon; alloys like 7075 may develop thinner coatings and perform inconsistently in corrosion tests.
• Exhibits poorer dielectric properties, making it less suitable for applications requiring electrical insulation.

• Salt Spray (Fog) Test per ASTM B-117: Verifies corrosion resistance.
